Applications of catalytic thermometric titrimetry to studies of molecular structure and reactivity. Part 2. Condensation and rearrangement reactions of carbonyl compounds

Abstract

Aliphatic and aromatic carbonyl compounds and some binary mixtures of these compounds are used as indicator reagents in the catalytic thermometric titration of benzoic acid with potassium hydroxide in propan-1-ol. Comparison of titration curves obtained in blank titrations and in titrations of benzoic acid are used to evaluate the relative reactivities of the carbonyl compounds when they undergo inter- and intra-molecular condensation and rearrangement reactions, and to investigate reaction processes with the binary mixtures. Consideration of the relative reactivities is used to establish relationships between reactivity and molecular environment of the carbonyl group.
